SAW-SET.

Specification of Letters Patent. i

Patented Sept. 26, 1916.

Application filed June 13, 1916. Serial No. 103,359.

To all 'whom 'it may concern Be it known that I, CHRISTIAN BoDMER, a citizen of the United States of America, residing at New Britain, Connecticut, have invented a new and useful Saw-Set, of which the following is a specification.

My invention relates to a new and improved tool for set-ting saw teeth, the main object being to provide a tool for that purpose which shall be so constructed and arranged as to operate with the greatest ease and eifectiveness, and which is capable of ready adjustment and which comprises a minimum number of parts so constructed and positioned as to permit the tool to be easily made and assembled.

In the drawings: F igure'l is a side elevation of my improved tool, the upper party being in section. Fig. 2 is a side elevation of the upper part of said tool. Fig. 3 1s a pla-n view of the tool. Fig. 4 is a cross sec-` tion on the line l-fl of Fig. 1. Figs. 5, 6 and 7 are perspective .views of details.

The main frame of the tool comprises the body 1, the forward end of which is widened at 2 and is provided with an oval sight opening. The rear end of the body 1 is provided with a rigid handle 3 which extends downwardly therefrom after the manner of the back of a pistol grip.

4 is an abutment shoulder at the meeting angle of the body 1 and the handle 3 which shoulder constitutes a thumb rest.

The underside of the body l is longitudinally hollowed out or channeled, and pivotally mounted at 5 in said hollowed out portion is a movable handle 6.

7 is a reciprocating plunger located in, and guided in, the channel in the underside of the body 1. The upper end of the handle 6 is provided with a suitable bearing 8 which projects into a recess in the underside of the plunger 7 whereby when the handle 6 is moved to and `fro the plunger 7 will be moved to and fro. Any suitable connection of course may be provided between the handle 6 and the plunger 7.

9 is a spring which normally operates to cause the handle 6 to stand in the position shown in Fig. 1 with the plunger 7 retracted.

The plunger 7 is preferably held in place by means of a removable block 10 which operates as a cap and which carries at its forward end a positioning face or gage 11 located underneath the oval opening in the part 2 of the body and standing slightly in front of the forward end of the plunger 7 when thek latter ris retracted. 'The cap 10 may be held in place in any suitable way as by pins 10a. l

.12 is an anvil block carried by the part 2 of the'body and arranged in front of the plunger 7. This anvil block is mounted in a vertical guide-way 14 at the forward side of the oval opening. The anvil block is provided with a bearing face 15 which is oblique relatively to the saw positioning face 11. The forward end of the plunger is provided with a central relatively narrow projection 16, the forward face of which is formed in a plane substantially parallel to the plane of the oblique face of the anvil.

17 is a screw which is carried by the anvil block 12 and passes through a vertical slot in the forward part 2 of the' body 1 (see Fig. 1). Mounted on the screw 17 is a nut 18 and thc inner end of the nut is preferably hollowed out to provide room for a coil spring 19.

2O is a washer arranged between the inner end of the nut 18 and the outer forward end of the body.

21 is a screw which projects up into the underside of the forward part 2 of the body. This screw 21 may have an annular flange 22 which takes into a notch the edge of the block 12 so that by adjusting the screw 21 up and down the block may be vertically adjusted whereby the degree of overlap between the part 16 and the face 15 may be varied to adjust the tool so as to secure the desired degreeof offset to the. saw teeth to be loperated on. `When the desired adjustment is effected the nut- 18 may beset up tightly to hold the anvil against movement.

In operation the toothed edge of the saw is slid into the spacebetween the face 11 and the block l2. The tool is then slid along the 1 .llO

lt will be observed that the parts are so arranged that the operating hand may be held in a natural position so that the tool can be operated for a long period without tiring the user. The leverage on the handle on the plunger is also such as to afford a great reserve of power. The construction is also such as to obtain evenness and uniformity in the setting of each tooth, it being essential to perfect work that all the teeth should be set alike.

lf desired, the anvil block l2 may have a serios of grad nations on its side, as shown in Figs. l and f3', to facilitato the easy and accurate adj ustment of the same, the graduations being read from the adjacent lower edge of the part 2.

rllhe entire structure .may be very quickly taken apart or assembled and in the event of breakage or loss of anyparticular part the sameina-y be quickly replaced. To remove the plunger 7 the pins 5 and 10a are simply driven out so as to release the handle G and cap 10 upon which cap the plunger is supported. When the cap l() is detached the plunger 7 is free. When the cap l() is in place it serves not only to hold the plunger T in its guiding channel, but it' also acts as a stop to limit the forward swinging movement of the handle 6.

l. ln a saw set, a frame comprising a body portion widened at its forward end and having a sight passage tl'ierethrough, a rigid depending handle at the rear end of said body, the underside of said body being channeled, a reciprocating plunger mounted in said channel, a pivoted handle operata/*ely connected with said plunger to reciprocate the same, arernovable block for the lower side of said body, a saw positioning gage at the forward end of` said block, a vertically adjustable anvil block in front of said plunger and saw positioning face, the operative face of said anvil and the cooperating face of said plunger being substantially parallel to each other and oblique to the plane of the face of said positioning gage.

2. ln a saw set, a frame comprising a body portion widened at its Vforward end and having a sight passage therethrough, a rigid depending handle at the rear end of said body, the underside of said body being channeled, a reciprocating plunger mounted in said channel, a pivoted handle operatively connected with said plunger to reciprocate the same, a removable block for the lower side of said body having a positioning face, a vertically adjustable anvil block in front of said plunger and saw positioning face, the operative face of said anvil and the co operating face of said plunger being substantially parallel to eachother and oblique to. the plane of saidv positioning face, said a reciprocating plunger mounted in saidchannel, a pivoted handle operatively connected with said plunger to reciprocate the saine, a removable block for the lower side of said body, a saw positioning gage at the forward end of said block, a vertically adjustable anvil block in front lof said plunger and saw positioning face, the operative gage of said anvil and the coperating face of said plunger being substantially. parallel to each other and oblique to the plane of the face of said positioning gage, and means for adjusting said anvil .comprising two screws arranged at right angles to each other.
